I have multiple years of experience in collection, invoice processing, financial reporting and reconciliation related tasks in multiple ERP systems.

Task automation

In case of repetitive, reporting, invoice processing or sometimes data downloading related tasks, a lot of time can be spared by automating a certain task instead of performing it daily.

If you have a re-occurring task that haunts your business life periodically (typically reporting, period-end closing or analytical tasks are like these), let's check it together. Maybe we can find a clever solution to automate it.

I work with AI tools to find the best possible solution to your business needs.
